2007-07-10Input: aiptek - kill aiptek_convert_from_2s_complement()Dmitry Torokhov
There is no reason to do that, just tell the compiler that we are dealing with signed values in buffer, that's it. Signed-off-by: Rene van Paassen <rene.vanpaassen@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2007-07-10Input: aiptek - use maps in attributesDmitry Torokhov
Use maps to convert for strings to internal constants and vice versa in aiptek's sysfs attribute methods instead of open-coding it. This results in smaller code that is also easier to maintain.

2007-07-10Input: aiptek - do not check for NULL in attribute methodsDmitry Torokhov
It makes no sense to check for NULL in attribute methods - we do usb_set_intfdata before creating attributes and once attributes have been removed we are guaranteed to not be called. Signed-off-by: Rene van Paassen <rene.vanpaassen@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2007-07-10Input: aiptek - do not try to export associated event deviceDmitry Torokhov
Do not try to export via sysfs associated event device - it does not work when evdev is a module that is loaded after aiptek; also it pokes too deply into input core internals.

2007-07-10Input: psmouse - add support for Cortron PS/2 TrackballsAristeu Rozanski
Cortron PS/2 Trackballs (700-0001A) report the 4th button using the 4th bit of the first packet (yes, it breaks the standard PS/2 protocol). This patch adds an extra protocol to generate BTN_SIDE based on the 4th bit. There's no way to detect those trackballs using any kind of special sequence, thus the protocol must be activated explicitely by writing into 'protocol' sysfs attribute: echo -n "cortps" > /sys/devices/platform/i8042/serio1/protocol Signed-off-by: Aristeu Rozanski <arozansk@redhat.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2007-07-10Input: xpad - add support for Xbox 360 gamepadJan Kratochvil
Xbox 360 gamepad is slightly different then the previous model so it has its own version of process_packet method. Detection of this new device relies on USB_DEVICE_INTERFACE_PROTOCOL macro. This device got vendor specific subclass so it can't be matched with USB_INTERFACE_INFO and we need only one interface protocol from four availaible. It means USB_DEVICE can't be used either. Added xpad360_btn structure with additional buttons for x360 gamepad. Added xtype into xpad_device structure to distinguish between different types of xbox devices.

2007-06-29Input: serio - take drv_mutex in serio_cleanup()Dmitry Torokhov
We need to take serio->drv_mutex in serio_cleanup() to prevent the function from being called while driver is in the middle of attaching to a serio port. Such situation can happen with i8042 and atkbd drivers if user rapidly presses Ctrl-Alt-Del during system startup, and leads to kernel oops.

2007-06-28Input: atkbd - throttle LED switchingDmitry Torokhov
On some boxes keyboard controllers are too slow to withstand continuous flow of requests to turn keyboard LEDs on and off and start losing some keypresses or even all of them. Delay executing of LED switching request if we had another one within 50 ms thus easing load on the controller. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

This should get rid of "atkbd.c: Suprious NAK on isa0060/serio0" messages caused by broken MUX implementation. The box does not have external PS/2 ports and, according to documentation, automatically disables touchpad when an external mouse is plugged into a port replicator, so MUX mode would not work anyway.

2007-06-03Input: reduce raciness when input handlers disconnectDmitry Torokhov
There is a race between input handler's release() and disconnect() methods: when input handler disconnects it wakes up all regular users and then process to walk user list to wake up async. users. While disconnect() walks the list release() removes elements of the same list causing oopses. While this is not a substibute for proper locking we can reduce odds of getting an oops if we wake up normal readers after walking the list. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

In commit [1] the SPI mode is set to 1, but it should be 0. As stated in the commit, ads784x samples the data on the rising edge. SPI mode 1 samples on the falling edge [2] though. The root cause of this is a bug in the omap_uwire code, which treats CPHA=1 incorrectly; so these two bugs cancel each other out on one of the main regression test platforms for this driver.

The i8042 driver fails detection of the AUX port with some chips, because they apparently do not change the I8042_CTR_AUXDIS bit immediately. This is known to affect at least HP500/HP510 notebooks, consequently the built-in touchpad will not work. The patch will simply reread the value until it gets the expected value or a retry limit is hit, without touching other workaround code in the same area.
